Circumference theorem
WebPerimeter is the distance around a two-dimensional shape. Example: the perimeter of this rectangle is 7+3+7+3 = 20. Example: the perimeter of this regular pentagon is: 3+3+3+3+3 = 5×3 = 15 . The perimeter of a circle is called the circumference: WebApr 11, 2024 · To find the octagon area, all you need to do is know the side length and the formula below: Octagon Area = 2 × (1 + √2) × a²; The octagon area may also be calculated from: Octagon Area = perimeter × apothem / 2. A perimeter in octagon case is simply 8 × a. And what is an apothem?
